INTER-TEL AXXESS
With a European System
7.36 Each type of station instrument is connected to a specific station card. Digital phones
are connected to Digital Keyset Cards (DKSCs) and/or 16-Port Digital Keyset Cards (DKSC-
16s). Analog phones are connected to Analog Keyset Cards (AKSCs). Single-line sets and
playback devices are connected to Single-Line Cards (SLCs) or 16-Port Single-Line Cards
(SLC-16s), or they can be connected to Single-Line Adapters (SLAs) which are in turn con-
nected to available DKSC/DKSC-16 circuits.
7.37 After the station cables are run, connect them to the station blocks on the MDF. Ensure
both ends of each station cable are labeled with the circuit number of the associated station
instrument. The station cables are pre-terminated on the upper half of the Krone block. The
line plant wiring extension terminates on the lower half of the Krone block. See
Figure 3-19
DKSC-16 Extended Loop Length Modification
7.38 For longer station loop lengths, an optional customer-supplied, external power supply
can be connected to the DKSC-16 termination block. You can use the Inter-Tel 30V power sup-
ply for 108 ohms/2100 feet (640 m). Or you can purchase the +36VDC External Power Supply
Kit (kit part no. 928.3705).
7.39 This option is available only on DKSC-16s that are at revision level "2.0" or later or
that have been modified and labeled with FSM100995. The external power supply is connected
to pins 50 (+36V, V/SL) and 25 (GND, SL/V) on the termination block. In addition, the strap
on jumper JP1 must be placed over pins 1 and 2 to enable the external power supply.
Installing SLC-16 Power Supplies
7.40 A power supply is required for each SLC-16 because the cards are not designed to pull
talk battery, ring, or message lamp power from the system power supply. Power supplies are
available that support one card or up to four cards.
7.41 There are two ways to connect the power supply to the SLC-16:

on the following pages for station cable termination.
Connect the power supply directly to the board using the RINGING POWER SUPPLY
connector on the SLC-16. See
Punch down the power supply wires at the MDF. See the diagram in
page 3-57 and the chart in
wires have to be cut off before the power supply can be installed.
If a four-card power supply is wall mounted, be sure that the fully enclosed side is on
page 3-118.
